The iterations \(p_{i} = f(\lambda (p_{i-1}))\)  converge asymptotically to \(p_\infty = 0\)  if the system load \(L < L^*\)  [1]}.
Here, \(L^*\)  is called the inflection load of the system: for any \(L \ge L^*\) , the system becomes interference limited and the \(\textsf {PLR}\)  does not converge to 0 as \(L\)  increases.
Thus, for \(L < L^*\) , \(p_\infty = 0\)  and therefore the asymptotic \(\textsf {PLR} = 0\) , and the throughput equals \(L\) .
For \(L \ge L^*\) , the throughput decreases monotonically with \(L\) .
